26 Claims.

My invention relates to improvements in safety controls for pressingmachines, preferably to pressing machines adapted for use in pressing;,garments and having fluid pressure actuated op- ,erating means.

ing juxtaposition and in which a separate handle is provided for eachhand movable for actuating purposes in a single direction only andpreferably also so constructed that in case one of the hands should slipoil, movement of one handle alone will automatically cause the device toseparate the pressing members so that there is no possibility ofaccident to the other hand. In my preferred embodiment each handle isactuated in the same direction to close the pressing machine, theactuation of one handle only in the same direction being operable toopen the pressing machine to separate the pressing members so that therecan be no possibility of accident.

A further object of my invention is to further insure the safety of theoperators hands by providing a latch which will not only not latch tokeep both hands occupied until both manual means are each moved to anactuating position, but also one which will not take effect until theyare then conjointly released, thereby keeping the operators handsoccupied until a definite mental step is necessary to effect theactuation of the latch.

As an additional safety feature, the pressing machine is preferably soconstructed as to employ only a relatively light pressure while bringingthe members into pressing juxtaposition, which pressure immediatelychanges to a relatively higher ironing pressure after there is no dangerof the hands being caughtbetween the pressing members. i A furtherfeature of my invention is to proing means when said pressing membersare brought into pressing juxtaposition to permit release of the handlesat substantially the instant when the device changes from theapplication of a light to heavy ironing pressure, thereby freeing theoperator's hands for other uses during the application of the heavyironingpressure.

A further feature of my invention is to provide the handles in a hiddenand yet accessible place where they will not catch on the clothes beingpressed and for this purpose I preferably locate them immediatelyunderneath the front end of the usual table and provide guard means,such as a downturned flange at the front of the table to protect thehandles.

Further features of my invention relate to improvements in the controlmeans for controlling the flow of fluid to the fluid motor for bringingthe pressing members into pressing juxtaposition.

One specific feature of the control means is that I employ a quickacting flush valve to rapidly exhaust the fluid motor to separate thepressing members, located in the feed line to the fluid motor,preferably immediately adjacent the fluid motor. To actuate said quickacting flush valve to quickly evacuate the fluid motor, I also provide ableeding trigger exhaust valve in said feed line and an inlet valve insaid feed line and suitable means to effect opening of said inlet;

valve and closing of said trigger exhaust valve substantiallysimultaneously toactuate the-fluid motor and closing of said inlet valveand opening of said trigger exhaust valve substantially simultaneously,the trigger exhaust valve functioning to release the quick acting flushvalve in the same feed line to immediately evacuate the motor. If thequick acting flush valve be not employed, or should fail in use, it isobvious that the exhaust valve itself may evacuate the fluid motor in aslower manner.

A further object of my invention is to simplify the control means forthe fluid motor by employing the inlet valve and thebleeding triggerexhaust valve in a single master valve with each valve controlled by asingle stem member. So far as I am aware this feature is new whether thequick acting flush valve be employed in combination with the mastervalve, vor otherwise.

A further feature of my invention resides in the fact that both theinlet'and exhaust valves of the master valve and the inlet and theexhaust portions of the'quick acting flush valve are selfvide meansautomatically operated by gravity and controlled by the pressing memberactuatclosing so that in order to cause actuation of all of said valvessimultaneously to actuate the fluid motor to bring the pressing membersinto pressing juxtaposition, or to evacuate said fluid motor to separatesaid pressing members, a single movement of the movable control memberin a single direction only is necessary, in. the embodiment shown, themovable control member and the vari ious valves being self-movable topositions evacuating the fluid motor when the movable control member isno longer restrained or moved to a position actuating the fluid motor tobring said pressing members into pressing juxtapositions.

Due to the aforedescribed construction employing the quick acting flushvalve, it is obvious that I am able to provide a preferably two-hand,manual control for the master valve, which same twohand controlfunctions. as a remote control through the medium of the flow of fluidthrough the feed line for the quick acting flush valve and it is thusapparent that I have provided a single manual control for actuating allof the valves employed in the system.

A further feature of my invention relates to the fact that I employ acheck valve in combination with the quick acting flush valve, inletvalve and bleeding trigger exhaust valve in the feed line whether or notsaid check valve, inlet valve and bleeding trigger exhaust valve areassociated together in a master valve, preferably a check valve of aself-closing type so that in case a plurality of pressing machine unitsare operated from a single source of fluid pressure, each one may beoperated independently without affecting the operation of the other,particularly in a manner to insure that the operation of one pressingmachine in the series will not affect the safety features of theimproved control means for the other pressing machines. With theemployment of a check valve it is obvious that the safety feature ineach of the units will be maintained in the case of failure of thecommon source of fluid supply.

A further feature of my invention is to provide a mechanism wherein eachstep changing the phase of operation of the device takes place with asharp and positive actuation. For this purpose I preferably provide thevarious types of check, inlet and exhaust valves employed with positiveself-closing features so that the transition from open to closedposition will take place rapidly. For the same reason I preferablyemploy a gravity actuated latch which will tilt sharply into a latchingposition. It is obvious that the instant actuation of a gravity actuatedlatch is highly desirable in the event the addition of a timingmechanism to the pressing machine is desired.

A further feature of my invention is that by the provision of suchself-closing valves and a gravity actuated latch I am able to provide amechanism which will function more quickly than prior art mechanismswhich depended for their similar actuation on the relatively slowmovement of the fluid in the cylinder.

Further features of my invention relate to improvements in the detailedconstruction of the handle operated actuating means, the specificconstruction of the quick acting flush valve, the

specific construction of the master valve and the. specific constructionof the various parts of my invention to make them practical for use in aspecific type of fluid motor actuating means for bringing the pressingmembers of a garment pressing machine into pressing juxtaposition andlater applying a greater ironing pressure, the

various parts of my invention being particularly constructed tocooperate with a linkage system for bringing the pressing members intopressing juxtaposition, including a link pivotable on one fulcrum tobring said members rapidly to a pressing position with relatively lightpressure and pivotable after a predetermined amount of its movement on adifferent fulcrum to automatically apply a greater predetermined ironingpressure to said pressing members.

A further feature of my invention is to provide a latch which willbejam-proof without danger of breaking the various parts thereof.

Further features of my invention relate to the specific construction ofthe various valves which make the feed line for the fluid motorsubstantially leak proof, particularly the specific construction of theleak-proof master valve.

These and such other objects of my invention as may hereinafter appearwill be best understood from a description of the accompanying drawingswhich illustrate embodiments thereof applied to a garment pressingmachine.

jamming of the latch and consequent breaking of the parts in use.

In the drawings, wherein like characters of l reference generallyindicate like parts throughmovable pressing members 22 and 24, in theembodiment shown, comprising the usual stationary buck 22 mounted-on thepressing. machine above the usual table 26 and the movable pressing head24 pivotally mounted on the machine frame 28 as at 30, in the embodimentshown, being mounted on the end of the power arm 34 of a lever of thefirst class 32 having a weight arm 36 extending rearwardly therefrom,weighted to normally pivot the pressing head 24 to an open position.

Suitable means are provided for moving the movable pressing head 24 intopressing juxtaposition with the buck 22, including a fluid motor 38 andmeans controlled by the fluid motor 38 for moving said lever 32 for thispurpose, in the preferred embodiment shown, comprising the speciallyconstructed linkage 40. Means are provided for controlling the flow offluid to said fluid motor 38, including a feed line 42 for said fluidmotor, an inlet valve 44 in said feed line and an exhaust valve 46 insaid feed line and means to effect opening of said inlet valve 44 andclosing of said exhaust valve 46 substantially simultaneously to actuatesaid fluid motor 38 to pivot said pressing head 24 into pressingjuxtaposition over the buck 22 and alternatively to close said inletvalve 44 and open said exhaust valve 46 substantially simultaneously toevacuate said fluid motor 38 to permit said weight arm 36 to pivot saidpressing head 24 away from said buck. In order to quickly evacuate thefluid motor to'permit rapid movement of'the pressing head 24 away fromthe pressing buck 22 I also interpose in said feed line, preferablyadjacent said fluid motor a quick acting flush valve 48 and where saidquick acting flush valve is employed, the exhaust valve 46 becomes atrigger exhaust valve to cause a drop of pressure in said feed line 42beyond said trigger exhaust valve 46 to cause the actuation of the flushvalve 48 in the automatic manner to be explained. If desired, however,the quick acting flush valve 48 may be dispensed with, but if it beemployed, a trigger exhaust valve 46 in the feed line is necessary toinitiate the actuation of the quick acting flush valve 48 in the mannerto be explained. Wher a plurality of press- 44 is of a self-closingtype, the check valve 50 is of a self-closing type and the bleedingtrigger exhaust valve 46 is of a self-closing type with the self-closingcheck valve 50, the self-closing inlet valve 44 and the self-closingbleeding trigger exhaust valve 46 being so arranged in the master valve52 that a single movement of the control member 54 inone direction isall that is necessary allowing line pressure to respectively open theinlet valve 44, open the check valve 50 and permit self-closing of thetrigger exhaust valve 46,

the stem member 54 being normally spring urged to a position opening theexhaust valve 46 and permitting self-closing of said inlet valve 44 andcheck valve 50. The master valve 52 is thus so constructed that a singlemovement of the stem member 54 away from its self-closing position willfunction to allow line pressure to open the inlet valve 44, open thecheck valve 56 and permit self-closing of the bleeding trigger exhausting units 20 are actuated by a single source of fluid supply, I alsopreferably employ in the feed line 42, a check valve to preventactuation of one unit from affecting the actuation of the other pressingunits 20 in the system. While I have shown my invention applied to agarment pressing machine, it may be employed in any type of a pressingmachine, such as a metal stamping machine, or a plastic molding machineand insofar as the controlling features of my invention,

are concerned, the specific type of control shown may be employed tocontrol a fluid motor 38 to actuate any type of a movable member,whether it be the pressing head 24, or any other movable member in anentirely different type of machine.

A further feature of my invention, which is particularly desirable inpressing machines, is that of locating the loleeding trigger exhaustvalve 46, the inlet valve 44, and the check valve 50, where employed, ina master control valve 52, the

movement of all three of these valves being controlled by the movementof a single stem memvalve 46. As explained, the quick acting flush valve48 is automatically self-opening when a drop in pressure occurs in thefeed line 42 due to opening of the bleeding trigger exhaust valve 46.One feature of my invention is that the master valve is substantiallyleak-proof for the selfclosing of the exhaust valve 46 takes place justprior to the actual opening of the inlet valve 44 and the self-closingof the inlet valve 44 takes place just prior to the opening of theexhaustvalve 46.

In the preferred form of master control valve 52 shown, said valve isprovided with a chamber 56, and the feed line 42 includes an inlet line58 connecting said chamber56 with the source of fluid pressure supplyand an outlet line 60 connecting said chamber 56 with the fluid motor38, or with the quick acting :flush valve 48 where employed. The inletvalve is provided at the inlet port of said chamber 56, the bleedingtrigger exhaust valve 46 is alsomrovided in said chamber 56 and thecontrol member 54 also is movable from a closed position in said chamber56 free of'said inlet valve 44 and retaining said exhaust valve 46 inopen position to an open position opening said inlet valve 44 andpermitting closing of said exhaust valve 46. Means such as the operatinglever or control member 62 operable from without said master controlvalve is provided to move saidv stem member 54 to said open position andspring means 6 is provided to normally urge said stem member 54 to aself- :closing position when said operating lever 62 is free. As alsostated, in the preferred embodiment shown, the inlet and check valves 44and 50 are of a self-closing ty e, the bleeding trigger exhaust valve 46is also of a self-closing type andv ing it and said stem member 54 inclosed position, moving said stem member 54 to a position opening saidinlet valve 44 and permitting selfclosing of said exhaust valve 46 andthat the means normally urging said stem member to a closed positionwill automatically function when pressure is removed from said operatinglever or control member 62 to move said operating lever I and stemmember back' to a closed position opening the exhaust valve 46 andpermitting selfber 54. In the embodiment shown, the inlet valve closingof said inlet and check valves 44 and 50.

In the preferred embodiment shown, my preferred type of master controlvalve is preferably constructed as follows: Said valve includes a casing64 (Fig. 1) having a chamber 56 divided into an inlet chamber 66 and anexhaust chamber 68. Said inlet chamber 66 has an inlet port I connectedby the pipe 58 to the source of fluid pressure supply and a check valveseat I2 surrounding said inlet port I0. The exhaust chamber 68 isconnected to said fluid motor 38, or to said quick acting flush valve 48by the pipe 60, as explained. The partition I4 extends between saidinlet chamber 66 and said exhaust chamber 68 and is provided withsuitable passage means I6 connecting said inlet and exhaust chambers 66and 68. The exhaust chamber is provided with the exhaust valve branch"I8 and the operating lever branch 80 projecting radially therefrom, inthe embodiment shown, being in diametric alignment. The inlet valve 44comprises an inlet valve seat 82 preferably of frusto-conical shape inthe lower end of said inlet chamber 66 around the upper end of saidpassage means I6. The check valve 50 includes a hollow cylindrical valveguide socket 84 having a side wall 86 slidably mounted in thecylindrical upper chamber 66 at a spaced distance from the wall 88thereof by means of the annular flanges 90 rigidly mounted atspaceddistances on said chamber Wall and provided with the plurality ofperforations 92 therein as shown in Fig. 5. Said valve guide socket 84,in the embodiment shown, is provided with a conical upper end 94 formingthe check socket 84 is also provided with the open lower end 96 locatedimmediately above said inlet valve seat 82. Spring means 98 comprisingthe helical spring 98 i 'contained within said socket 84. The

inlet valve 44 comprises a suitable valve, in the embodiment shown, aball valve normally urged to a seated position on said inlet valve seatby said seating spring means. Said seating spring means 96 alsofunctions to normally move said ocket 84 to seat its conical upper end94, comprising the check valve 50 in a self-closing manner on'its checkvalve seat I2. In the embodiment shown, saidpassage means I6 comprises acylindrical bore I00 of substantial diameter at the upper end thereofand a plurality of passages I02 flaring radially outwardly anddownwardly to discharge in the upper end of said lower exhaust chamber68 (Fig. 6).

An inlet valve stem 54 is provided for vertical reciprocation withinsaid exhaust chamber 56. Said valve stem 54 has an upper end I04 adaptedto about said ball inlet valve 44 to raise it aga nst the pressure ofthe spring 98 to unseat said ball inlet valve 44 to open said inletvalve. Said valve stem 64 is provided at a point intermediate the endsthereof with the flange means I 06 projecting radially therefrom, in thepreferred embodiment comprising a disk I06. The valve stem 54 isreciprocatably mounted in said exhaust chamber 68 with the upper end.I04extending through said passage bore I00 and into said inlet valvechamber 66 to unseat said ball inlet valve 44. Means are provided tovertically align said valve stem for vertical reciprocation within saidexhaust chamber 68 and passage means E6, in the preferred embodiment,said. .means comprising a hollow stud I08 having a central bore H0discharging into said passage bore I00 for containing the upper end ofsaid valve stem 54 and projecting vertically downwardly from the upperend of said exhaust chamber 56 between the lower ends of said radialpassages I02. Said aligning means also includes, in the embodimentshown, a hollow stud I I2 projecting externally downwardly from saidcasing 64 having a bore II4 to receive the lower end of said stem 54. Ahelical spring I I6 is provided in said lower exhaust chamber 68abutting said disk I06 or flange means and the upper wall of said lowerchamber between said radial passages I02 to normally urge said valvestem member 54 to closed position free of said inlet valve 44 to permitthe normal self-closing or seating of said inlet valve 44 and said checkvalve 50 by said expansion seating spring means 98.

A self-seating exhaust valve 46 is provided in the exhaust valve branch18 of said exhaust chamber 68. Said exhaust valve 46 includes aperipheral shoulder II8 projecting radially inwardly in the inner end ofsaid exhaust branch I8 and an exhaust port I20 in the outer end of saidexhaust branch I8 having an exhaust valve seat I22 at the inner endthereof, in the embodiment shown of frusto-conical shape. The exhaustvalve proper 46 has a surface I24 seatable on said exhaust valve seat,in the preferred embodiment, comprising a partially spherical surfaceI24 to cooperate with said frusto-conical valve seat I22. In theembodiment shown, the exhaust valve 46 has an annular disk I26perforated as at I21 projecting radially outwardly therefrom as shown inFig. 7 terminating in an outwardly projecting peripheral flange I30. Anexhaust valve stem I32 projects inwardly from said valve 46 terminatingin an inner end I34 preferably spherically enlarged, as shown,contacting the disk I06 of said inlet valve stem 54. Spring means, suchas the helical spring I36 is provided in said exhaust branch 18-surrounding said valve stem I32 and having an inner end abutting saidperipheral shoulder II8 and an outer end abutting said perforatedexhaust valve disk I26 to normally urge said exhaust valve 46 to aseated position on its valve seat I22 with the peripheral flange I30abutting the outer end of said exhaust branch 18 exterior of saidexhaust port I20 when the enlarged inner rod end I34 is free of saidinlet valve stem disk I06.

Said master valve also includes an operating lever or control member 62nonleakably universally pivotally mounted in the end wall I40 of saidoperating lever branch 80 having an inner end I38, preferablyspherically enlarged, as shown, underlying said inlet valve stem diskI06. For this purpose, a port I42 is provided in the end wall I40 ofsaid-outlet branch having an outwardly diverging wall I44 and apartially spherical socket I46 in the inner end thereof. In theembodiment shown, the outwardly diverging portion I44 comprises aseparate extension from the outer wall I40 of said operating leverbranch 80. The control lever 62 has a spherical pivot enlargement I48centrally thereof seated in said partially spherical socket I46 foruniversal movement of said control lever therein. The enlarged sphericalinner end I38 of said control lever 62 contacts said valve stem diskI06. The outer end I50 of said operating lever or control member thusproiects outwardly through and beyond the outwardly diverging internalwall I44 of said outlet port I42 or extension I52, through and beyondthe end of said port or extension I52 abutting the wall of said port orextension to limit the umversal movement oi the outer end I88 of saidoperating lever or control member 82. To render the operating leverbranch leak-proof I preferably provide a sealing spring washer I64having a central hole I68 adapted to overlie the inner endof thespherical enlargement I48 to normally urge it outwardly to continuouslyabut and cover the inner surface of said spherical lever pivot portionI48 to positively prevent leakage of air through said port I42 into saidoperating lever branch 88.,-

Any suitable type. of means may be provided to operate said mastercontrol valve by the depression of the outer end I58 of said operatinglever or control member 62.- The exhaust valve branch 18 exterior ofsaid exhaust port I28 may be provided with suitable sound deadeningmeans I68, such as felt, or otherwise, to muille the changes in the flowof air-through said valve.

As stated hitherto, I preferably employ a quick acting flush valve 48interposed in said feed line 42 beyond said trigger exhaust valve 46.Said flush valve includes a chamber I68 having an in let port I 62, anoutlet port I64 and an exhaust port I66, an exhaust valve I 68 to closesaid exhaust port I66 normally urged to an open position, an inlet valveI18 connected to said exhaust valve controlled by a drop of pressurefrom said inlet port I62 caused by bleeding of said trigger that. fluidpressure from said-inlet line 42, on opening of said inlet valve 44,will raise said flush valve inlet valve I18, said connected valve stemI84 and said connected exhaust valve I88 to a position closing saidexhaust port I 68 and that said inlet valve I18, connected valve stemI84 and said connected exhaust valve I68 will drop on reduction-ofpressure in said feed line to open said exhaust port I66 and close saidinlet port I62. I also provide a combination check and differentialvalve I12 in said inlet chamber I16 preferably of flat annular formationand of a size to seal said vent means I86 in said inlet valve I18. Ialso provide spring means I98 in said chamber I68 abutting said checkvalve I12 of a strength to normally urge said check valve I12 to aposition sealing said inlet vents I86, namely, with said check valve I12covering and closing said vent means I86, said spring means I98 beingyieldable, however, to permit sustained pressure in said line to raisesaid check and differential valve I12 against the pressure of saidspring I88 to permit fluid to flow through said vent means I I86 aroundsaid spring I98 in said inlet chamexhaust valve 46 to permit backpressure from said fluid motor 38 to rapidly close said inlet port I62and open said connected exhaust valve I 66 and a self-closingcombination check and differential valve I12 in front of said exhaustvalve I68 and in rear of said inlet valve I18 to prevent back pressurein said line 42 and effective on sustained pressure in said line toadmit fluid pressure through to said fluid motor 88.

In the preferred embodiment, said quick acting flush valve is preferablyconstructedas follows: The chamber I68 is divided into an upper exhaustportion I14 and a lower inlet portion I16 connected by the passage meansI18. The inlet chamber I16 has the inlet port I62 in the lower wallthereof connected to the exhaust chamber 68 of said master valve by thepipe portion 68 of said feed line 42. The exhaust portion I14 has theoutlet port I64 therein and the exhaust port I66 therein in verticalalignment with the inlet port I62 in said inlet chamber I16. The exhaustport I64 is connected to said fluid motor 38 by the pipe I88 formingpart of the inlet or feed line 42. The exhaust port I66 is provided with,the exhaust valve seat 182, preferably of partially spherical shapeextending around said exhaust port. The valve stem I84 is mounted forvertical reciprocation within said chamber I68 and projects verticallyupwardly through said inlet chamber l16, said pa'ssagemeans I18 and saidexhaust chamber I14. Said valve stem I84 is provided with the inletvalve I18 on the lower end thereof adjacent said inlet port I62comprising in the preferred embodiment shown, a disk valve I18 ofsubstantially the circular or other area of said inlet chamber I 16adjacent said inlet port I62 having a plurality of vents I86 thereinexterior of said inlet port I62 preferably arranged in annular formationexteriorvof said inlet port I62 as shown in Fig. 8 providing a solid.central portion I88 for sealing said inlet port.

I62 to provide an inlet valve. The exhaust valve I68 is mounted on theopposite end of said stem I 84 in said exhaust chamber I14 andpreferably comprises a spherical valve I68 adapted to seat in saidpartially spherical valve seat I 62 sur-- rounding said exhaust portI66. It is apparent 7 ber I16 through said passage means I18 and outthrough said outlet port I 64 and through said pipe I88 to actuate saidfluid motor 38. Exhausting of pressure in said feed line 42 due toopening of said bleeding trigger exhaust valve 46 will inevitably permitlowering of said inlet valve I 18, valve stem I 84 and connected exhaustvalve I 68 to permit rapid evacuation of fluid from said fluid motor 38through said pipe I 88, outlet port I62, exhaust chamber I14 and exhaustport I 68. In the embodiment shown the other end of the spring abuts thelower surface of the ball exhaust valve I68. If desired, the entireflushvalve may be inverted.

As stated hitherto, I believe the novel features of structure of myimproved quick. acting flush valve are also novel. As also statedhitherto, it is apparent that insofar as certain aspects of my inventionare concerned, the quick acting flush valve 48 may be omitted ifdesired;

As stated hitherto, my invention also includes safety means, including apair of handles I92 for actuating the fluid or other motor employed tobring the pressin members 22 and 24 into pressing juxtaposition.Features of my invention reside in the facts that the handles I92 areonly effective on a single movement thereof in a single direction toaffect the controlling means for the fiuid motor and that they areoperableto actuate the controlling means for the motor to bring saidmembers 22 and-24 in pressing juxtaposition only whenflboth of saidhandles I 92 are moved-together, movement-of one of said handles I92---only being operable to a'ilectsaid controlling means to separate saidressing members. It is thus obvious that during the dangerous periodofrelative movement of said pressing members 22 and 24 topres'singjuxtaposition,

both'of thev operator's hands are employed on the respective handles I92to cause such movement and that if anything should happen causing theremoval of a hand from one of thehan'dles, the device will automaticallyfunction to positivelyeffect relative opening movement of said p ns'fmembers.

A further desirable feature of my preferred embodiment therefore is thateach of the actuating means is moved in the same direction to release tosafety position as to move the device to a pressing position, both ofthe handles, however, being required to efi'ect movement of the machineto a pressing position. Insofar as this feature of my invention isconcerned, it is apparent that any type of motor may be employed to movethe members 22 and 24 to and from pressing positions. As statedhitherto, I preferably employ the fluid motor 38'for this purpose. Asmost types of pressing machines are provided with a table 26, I havefound that an ideal place for the mounting of the handles is below thefront end of said table where they will not catch upon the clothes orother material being operatedon. The respective handles I92 arepreferably provided of a relatively large area so that they may beaccessible from various points along the front of the machine. Ifdesired, guard means, such as the flange I94 (see Fig. 9) projectingintegrally downwardly from the front end of the table 26 may be providedto further protect the handles. Any suitable type of handles, however,may be employed, such as the operating buttons I92 shown in Fig. 11,each of which actuates an axially slidable wire I96 encased in asuitable protective armored cylindrical flexible casing I98. The type ofhandles or buttons shown in Fig. 11 are particularly desirable whenremote control over a machine at a distance is desired, or a pluralityof machines assembled to operate as a unit are employed. As stated, onefeature of my invention consists in the fact that movement of bothhandles in a single direction is required to actuate the controllingmeans to bring the pressing members into pressing juxtaposition andwhile movement of one handle only is preferably employed to release saidmembers from pressing juxtaposition, other tyes of means to release'said members or to evacuate the fluid motor for this purpose, such asshown in my copending application for patent on Control means a forpressing machines, Ser. No. 376,286, filed January 28, 1941, maybeemployed. While any type of means may be employed to move the movablestem member 54 to actuate the inlet valve 44 and the exhaust valve 46and any type of means for controlling the motor or the flow of fluid toa fluid motor may be employed with my improved handles just described,best results may be obtained when my improved handle means are employedto regulate the inlet valve 44 and exhaust valve 46 through the movementof the movable stem member 54 in association with the specificcontrolling means shown and to be described. In the embodiment shown,both the fluid flow controlling means and the handle means forcontrolling the movement of the movement control member 54 areparticularly designed to cooperate with each other for use in a garmentpressing machine and hence, in the preferred embodiment shown, therespective handles I92 are designed and constructed to actuate themovable stem member 54 of the master valve 52 through the medium of theoperating lever or control member 62. When employed for this purpose,the respective inlet valve 44, check valve 50 and trigger exhaust valve46 are preferably self-closing in the manner previously described, sothat when both handles I92 are not actuated, the operating lever 62 willbe immediately released to a safety position closing the inlet valve 44and opening controlled by the actuating means for bringing the pressingmembers 22 and 24 into pressing juxtaposition; substantially when saidpressing members 22 and 24 have been brought into pressingjuxtaposition, to permit said controllin means to continue to functionto permit actuation of said fluid motor to apply ironing or otherpressure without further actuation of said respective handles I92,freeing the hands for other uses on other machines, if desired, whilethe ironing pressure is being applied.

Any means may be provided to release the movable control member 62 tofree it from said latch 200 to exhaust the fluid motor 38 to separatesaid pressing members.

If desired, means may be provided to bring said members 22 and 24 to apressing position with relatively light pressure and to automaticallyapply a greater predetermined ironing pressure to said pressing membersafter they have been brought into pressing juxtaposition. My inventionis particularly applicable to a pressing machine employing this greaterironing pressure, for not only, are both hands kept occupied during thedangerous period of bringing the members into pressing juxtaposition,but also said members are brought together with relatively lightpressure during this dangerous period. To achieve this result Ipreferably employ a modification of the linkage system shown in PatentNo. 1,897,689 for Actuating mechanism for garment pressing machines andPatent No. 2,026,- 264 for Garment pressing machine, in association withthe fluid motor 38, wherein one link 202 is pivotable on one fulcrum 204to bring said members to pressing position with relatively lightpressure and automatically pivotable after a predetermined amount of itsmovement on a different fulcrum 206 to apply a greater ironing pressureto said pressing members. Means are provided actuated by said linkage tomove the latch 200 to a position overlying the outer end I of theoperating lever or control member 62 substantially at the instant thepressing members 22 and 24 are brought into pressing position and thefulcrum of the link 202 has changed from 204 to 206 ceasing theapplication of relatively light pressure to said pressing members 22 and24 through the fulcrum 204 and initiating the period of heavy ironingpressure to said pressing members through the fulcrum 206. It is thenobvious that as the outer portion I50 of said operating lever 62 is thenbrought to a position underthe outlet valve 46 permitting immediatesepahitherto described, means preferably comprising gravity actuatedlatch means 200 automatically lying the latch 260, the device will beheld in a position supplying fluid to said fluid motor to exert greaterpredetermined ironing pressure and permitting release of the handles I92and that the latch 200 will only take effect when both handles arereleased together. It is then obvious that if one of said handles I92only be moved, as shown in Fig. 4 in dotted lines, that it will functionto knock the outer end I50 of the operating lever or control member 62free of said latch 200 to permit self-closing of said inlet valve 44 inthe manner explained and immediate actuation of said trigger exhaustvalve 46 to cause immediate relative separation of said pressing members22 and 24. It is obvious that so far as the means preferably comprisinglatch means for hblding the master valve or inlet valve open to actuatethe fluid motor 38 is concerned, that any type of control means formoving the outer end I50 of the operating lever or control member 62 maybe employed, but that greater safety aaeaasa 7 can be effected ii thepair of handles I02 hitherto described beemployed, operable when bothare moved to actuate the fluid motor to bring the pressing members intopressing juxtaposition and operable when one only is moved to evacuatethe fluid motor to permit the separation of said pressing members.Inasmuch as all of'these safety features are preferably employedtogethen'I will now describe in detail the specific type of handles,specific type of linkage and the specific type of latching meanspreferably employed by me.

As stated hitherto, means are provided to depress the outer end I50 ofsaid operating lever or control member 62 to raise said inlet valve stemmember 54 through the medium of the disk I06 against the pressure of thespring I I6 to raise said inlet valve stem 54 to abut said inlet valve44 to open the inlet valve to permit flow of fluid to the fluid motor 30and to permit self-closing of said exhaust valve 46, to cause said fluidmotor 38 and linkage 40 where employed, to relatively move said pressingmembers 22 and 24 to said closed pressing position. Said means includesa pair of cams 208 having upwardly tapered inner edges 2I0 forming, whenin raised position, a crotch 2I2 between them in which the outer end I50of the operating lever or control member 62 is adapted to liewith theoverlapping inner cam ends normally overlying said outer end I50 when itis in its. raised position.

Said cams are each mounted on respective arms 2 projecting forwardlyfrom and pivotally mounted on the master control valve 52 as at 2I5. Thepair of control handles I92 is provided, each extending underneath thefront end of the table 26 and each connected to a pivotally mounted camarm 2 in the manner diagrammatically shown in Figs. 1-4 by the link 2I0, or specifically as shown in Figs. 9 and 10 by an arm 2I8, having thelower end thereof engaged within a suitable groove 2I8 in said cam arm2. With this construction, it is obvious that when both said handles I92are raised, said cams 200 are conjointly lowered to depress the outerend I50 of the lever or control member 62 in the crotch 2I2 between themto move said stem member 54 to open the inlet valve 44 and permitself-closing of said exhaust valve 46 to causeflow of fluid to saidfluid motor 38 to relatively move said pressing members to closedposition. It is also obvious that when either handle I92 is raisedalone, no crotch 2 I2 will be provided to become effective to lower theouter end I50 of the operating lever or control member, but that theoperating lever end I50 will be merely pivoted sidewise so that thespring I I5 may function to maintain or move the control member 54 andoperating lever in or to a closed position closing the inlet valve andopening the exhaust valve to evacuate the fluid motor 38 to permit theweighted arm 35 to raise the, pressing head 24 to open position.

As stated hitherto. I also provide the latch means 200 effective tolatch the outer end I50 of the operating lever 62 in a depress d openpostion maintaining the inlet valve 44 open and the exhaust valve 46closed to continue to apply fluid pressure to the fluid motor 38 asshown in Fig.3

200 is thus pivotal on the pivot 20I from a position free of the outerend I40 of said operating lever or control member '02 as shown in Fig. 1to a position overlying said operating end as shown in Figs. 2 and 3after said pressing members have been brought to a pressing position,in'the preferred embodiment shown, substantially when the link 202 haschanged its fulcrum from 204 to i sure. In the preferred embodiment, thelink 220 is provided with a boss 222 adapted to abut a pin 224projecting laterally from the weight arm 226 of the latch 200. In theembodiment shown, it is obvious that when either handle I92 is raisedalone as shown in dotted lines in Fig. 4, that the respective ca'msurface 2I0will knock the outer end I 50 of the operating lever '62laterally free of the latch 200 to permit the spring H6 to immediatelyraise theouter end I50 of the operating lever-or control member and tolower the stem member 54 to permit self-closing of the inlet valve 44and to open the exhaust valve 45. It is obvious that when the latch 200has functioned to overl e the depressed outer end I50 of the operatinglever or control member after the handles I92 have been simultaneouslyactuated to simultaneously depress the cams 208 to. lower the outer endI50 of the operating lever in the crotch between them,

that said latch 200 will function to retain said 22. A stated, any meansmay be provided to re-, I

outer end in depressed position opening the inlet valve 44 andpermitting closing of the exhaust valv 40 to continuously apply fluidpressure to the fluid motor, and where the link 202 is employed, withgreater pressure, for the desired ironing interval. It is obv'ous thatwhen the inlet valve 44 is closed and the trigger exhaust valve 45opened on raising of the outer end i 50 of the operating lever that theflush valve 48. where employed, will function to quickly/evacuate thefluid motor to permit the weight arm 26 to raise the pr ssing head 24away from the pressing buck lease the latch 200 from the outer end I50of the operat ng lever or control member I50fand .for this purpose I mayprovide a supplementalloot lever 228 to actuate a link 230 to raise thelatch arm 226 to pivot the latch 200 free of the outer end I50 of saidoperating lever 52, such means being alternative or supplemental to themeans previouslydescribed for unlatching the latch.

It is apparent that with the construction hitherto described, the latch200 is gravity actuated by the weight of the weight arm 220' thereof andthat the link 220 abutting the pin 224 of said weight arm 226 preventsthe latch fr'om be'ng moved into latching position until the pressingmembers 22 and 24" have substantially reached a closed pressing positionwhen the link 2201 will have been lowered to theposition shown in Fig.3.by the respective movements of the parts of the l nkage 40 caused byactuation of the fluid motor 38. It is apparent that with thisconstruction a sharp gravity actuation of the latch 200 will beprovided, sharper than where th locking of the mechanism is diupwardlyfrom said link 220 to overlie the pin 224 and retain it in a position atall times immediately overlying the upper surface of said link 220, asshown in Fig. 12. With this spring construction, as shown in Fig. 13, itis obvious that the spring 225 may yield to prevent jamming andconsequent breaking of parts, should the point of the latch abut the endI50 of the operating lever or control member during its pivotalmovement. The embodiment of latch, I have shown in Figs. 1-4 will alsonot jam, the latch itself merely tilting should its point abut the endI50 of the operating lever 62 during its pivotal movement, and it isapparent that in both the embodiment shown in Figs. 12 and 13 and theembodiment shown in Figs. 1-4 that I have provided jam-proof structures.g

In place of the latch means 200 automatically operated by said actuatingmeans when said pressing members are brought into pressing juxtapositionto permitrelease of said handles while said controlling means continuesto function to permit further actuation of said fluid motor to applysaid ironing pressure, any other type of latching means may be employedfor this purpose, such as the type of means shown in my copendingapplication, S. N. 376,286, filed January 28, 1941, for Control meansfor pressing machines, effective to release similar respective handleswhile the ironing pressure is being applied and in addition any suitabletype of means to evacuate the fluid motor may be employed, such as themeans shown in said application. It is immaterial whether said latchingmeans be controlled by the linkage as shown herein, or be controlled bythe rising of the pivoted cylinder as shown in said application, bymovement of the pressing head, by the flow of fluid, or otherwise. Ifdesired, any suitable means and manually operated control therefor maybe employed to evacuate the fluid motor other than the specific typeshown.

I have also shown in Fig. 12 a structure analogous to that shown in saidcopending application, wherein the cylinder 246 of the fluid motor 38itself actuates the link 220 in place of having the movement thereofcontrolled by the motion transmitting mechanism or linkage 40. In thisconstruction, the link 220 is not pivoted on the same pivot as the latch200, but is pivoted at the point 23I as a lever of the flrst class. Therear end of said link 220 is pivotally attached to a rod 233 having anelongated slot 235 at the lower end thereof receiving a pin 23!projecting laterally from said cylinder, the slot 235 being of such alength as to become operative to tilt the front end 239 of the link 220downwardly when the cylinder 246 has been actuated substantially farenough to substantially close said pressing members 22 and 24.

I have shown in Fig. 11 a pair of an alternative type of handles I92,each effective to axially move a wire I96 encased in a flexible armoredcable I98 to raise arespective rod 232 to abut a respective arm 234projecting rearwardly from a cam arm 2I4, to lower the respective cams208 together when both of the respective buttons or handles 192' aredepressed together to lower the outer end I50 of said operating lever orcontrol outer end I50 of said operating lever 62 from the latch 200 topermit a quick evacuation of said fluid motor 38 for separation of saidpressing members 22 and 24. In the embodiment shown, each operatinghandle I92 comprises a socket I having a stem 236 projecting downwardlythrough a bore 238 therein connected to an end 240 of the axiallymovable wire I96, said button or handle I 92 being normally urged to araised position by a spring 242 contained in said socket 24I underneathsaid button I92. While I have shown in Fig. '11 the operating buttonsI92 and the cable encased axially movable wires I96 as an alternativeconstruction to the handles I92 shown in Figs. 1-10, it is obvious thatthis particular structure of cable encased axially movable wire I96 maybe readily employed for any purpose of handle may be employed therefor,it is apparent I that movement of either handle alone before or afterlatching will function to release the press, the depression of onehandle alone prior to latching causing the end I50 of the operatinglever or control member 62 to ride up the single cam surface and theactuation of a single handle after latching, similarly functioning topermit the spring I I6, to urge the outer end I50 of the operating leveror control member 62 upwards, the respective cam surface in thisinstance also functioning to move said end I50 of the operating lever 62laterally free ofsaid latch to permit said spring II6 to force itupwards along said cam surface. It is obvious that the specificstructure of the internal wall I44 of the exhaust branch port I42permits and limits the necessary movements of the end I50 of theoperating lever 62 for this purpose.

I have shown in Fig. 1 my device in a static position with the pressingmembers in relatively open position. When both operating handles I92 aremoved, as shown in Fig. 2, the outer end I50 of the operating lever orcontrol member will be lowered by the cams 208 to raise the stem member54 to open the inlet valve 44. against the pressure of the springs H6and 98 and raise the disk I06 free of the exhaust valve stem I32 tocompress the spring 98 to permit the socket 84 to slide to open thecheck valve 50 to permit fluid to be passed to the flush valve 48 asindicated in Fig. 2 by the arrows. Fluid flowing through the inlet portI62 of the flush valve 48 will then conjointly raise the inlet valve I10and differential valve I12 and lift the connecting valve stem I84 andconnected exhaust valve I68 to close the exhaust port I66. Sustainedpressure through said inlet line will then raise thedifferential valveI12 free of the ducts I86 compressing the spring I90 for this purpose soas to permit flow of fluid through the flush valve 48 out the outletport I64 thereof and pipe I to the fluid motor 38 pivotally mounted onthe pivotpin 244 on the front end of the machine frame 28. The fluidmotor 38 comprises the cylinder 246 pivotally mounted as at 244 on saidframe and the piston head 248 axially movable in said cylinder toactuate the piston rod III connected to the linkage II. The flow offluid to the fluid motor II will urge the piston rod III outwards, thelink II: functioning on its fulcrum III to move the pressing head IIrapidly towards the buck with light pressure. When theparts' haveassumed the position shown in Fig. 2. the'latch III will overlie theouter end III of the operating lever II. The link I" actuated by thelinkage II will bewithdrawn from the latch III substantially at theinstant shown in Pig. 2 when the pressing head is brought into pressingjuxtaposition with the buck 22 to permit instant gravity actuation ofthe latch III to latch the outer end III of the operating lever ,or

control member II in this position to permit re-! lease of the handlesIII as shown in Fig. 3 with said latch then retaining the mastervalveII-a'nd flush valve II in a position permitting the ingress ofsupplemental fluid to said fluid motor II to urge the piston thereof tothe position-shown in Fig. 3, the link 2|! pivoting on the point I as afulcrum to apply the ironing pressure. When the piston III has reachedthe outer end of its stroke in the cylinder, the differential valve I12in the flush valve will then be lowered by the spring III due to asubstantial equalization of pressure in the cylinder I and inlet lineII, .to cause said valve I12 to function as a check valve.

When it is desired to release the pressing members, one handle I92 maybe raised as shown in dotted lines in Fig. 4 to permit the cam surfaceIII thereof to knock the outer end III of said omrating, lever orcontrol member I2 laterally free of the latch III as shown in the dottedline mid position shown in Fig. 4, permitting the spring IIIto.='urge'the control member II downwards and rapidly raise the outerend III of said operating lever; or control member to its upper staticposition. As the valve stem member II is urged downwards, it is apparentthat the disk III thereof will abut the exhaust valve stem III to tiltthe exhaust valve II to the open position shown and that the sternmember II will belowered free of the inlet valve II so that the springII will immediately function to close the inlet volve II andsubstantially simultaneously close the check valve II. As pressure inthe master valve I2 is released by the trigger exhaust valve II,pressure will fall in the pipe II in such a deree as to permit thespring III in the exhaust valve II to urge the difl'erential valve I12to close the inlet ventmeans III in said inlet valve I10 and said fluidpressure will force the inlet valve "I, the connected valve stem III andexhaust valve III to open the exhaust port III in the flush valve IIpermitting the rapid discharge of fluid from the cylinder III backwardsthrough the connecting pipe III and out through the exhaust port III topermit the weighted lever arm II to lower the linkage II to move thepiston 248 within the cylinder 2 to exhaust the fluid out of the fluidmotor II and out said exhaust port III.

It is thus apparent that I have provided a novel type of safety controlfor pressing or other machines preferably one employing a fluid motorwith the advantages described above. I

It is understood that my invention is not limited to the speciflcembodiments shown and that various deviations may be made therefromwithout departing from the spirit and scope of the appended claims.
